废话不多说了，直接给大家贴代码了，具体代码如下所示：
<script type="text/JavaScript">
//获取url中的参数
$(function(){
var userName = window.location.href;
var aa = userName.indexOf("=");
console.log(userName);
if (aa == -1)
return "";
userName=userName.substring(aa+1);
//给hidden赋值并显示
$("#userName").val(userName).attr("type","text");
//ajax请求修改密码
var rePassword = $("#repeatPassword").val();
//6到15位字母或数字
var reg=/^[0-9a-zA-Z]{6,15}$/;
//新密码校验
$("#newPassword").blur(function(){
$("#msg").css("display","none");
var newPassword = $("#newPassword").val();
if(newPassword==""||newPassword==null){
$("#msg").html("请输入新密码！").css("display","block");
}elseif(!reg.test(newPassword)){
$("#msg").html("密码格式不正确,请重新输入！").css("display","block");
}
});
//重复密码校验
$("#repeatPassword").blur(function(){
var newPass = $("#newPassword").val();
var repPass = $("#repeatPassword").val();
if(newPass != repPass){
$("#msg").html("两次输入密码不一致,请重输！").css("display","block");
}
});
//表单提交前校验
$("#updateBtn").click(function(){
var flag = true;
var newPass = $("#newPassword").val();
var repPass = $("#repeatPassword").val();
var reg1=/^[0-9a-zA-Z]{6,15}$/;
if(!reg1.test(newPass)||newPass!=repPass||newPass ==""||newPass==null){
flag = false;
}
if(flag){
$.ajax({
url:"/HuaMuWebsite/userManage/editPassword?userName="+userName,
type:"POST",
async:false,
data:$("#fm").serialize(), //表单数据序列化, 可以对form表单进行序列化，从而将form表单中的所有参数传递到服务端。
success:function(data){
//json字符串转为json对象
var jsonObj=eval("("+data+")");
if(jsonObj.success != null){
alert(jsonObj.success);
window.location.href="/HuaMuWebsite/admin/login.html" rel="external nofollow" ;
}else{
alert(jsonObj.failure);
}
},
error:function(e){
alert("请求出错！");
}
});
}
});
});
</script>
